✦ Synopsis

CompHEP is a powerful system for calculation in HEP. One of the advantage of the CompHEP is the possibility of using user-defined QFT models. However, the model has some restrictions. In particular it cannot contain vertex which depends on a scalar function of the incoming momentum, so called form factor. One of the non-trivial examples of such model is SUSY. Authors describe an approach to the implementation of such objects in grid-oriented version of CompHEP.
